Cibachrome and Ilfochrome.

As in "Ciba-Geigy" (probably misspelled!) and "Ilford Chemical",
French and British Chemical companies, respectively.

You can also get Type R (reversal) prints on Fuji paper, which are
cheaper than Ilfochrome and a bit less contrasty, but with less intense
colors. It does really depend on the slide, and on how much you're
willing to pay. It is much easier to get a good print from an
interneg (having done all three types myself over the years), most
gallery prints on Ilfochrome are done with a contrast mask (a way
of reducing contrast I won't describe in detail) which is difficult
to do with 35mm (for reasons I also won't describe).

Galleries use Ilfochrome in part because the dyes used should last
for a few centuries if displayed correctly, but I don't worry about
this with my own stuff :)
